Hi, I'm Tyler 👋 — I build and ship full-stack products, with AI and reverse-engineering in the toolkit.

I run Golden Rock, where I build production web apps end to end: Next.js / TypeScript front ends, Node and Python back ends, PostgreSQL, Stripe billing, Docker, deployed on Google Cloud and Cloudflare. I put AI agents into real products — retrieval over your own data, scoped per customer, with a human in the loop for anything sensitive — and I do reverse-engineering work, recovering how undocumented apps, APIs and binaries actually behave.

What I do well

  • 🚀 Take over an existing codebase and get it over the line — without a rewrite
  • 🔒 Ship multi-tenant SaaS that keeps each customer's data properly isolated
  • 🤖 Wire AI assistants/agents into B2B apps so they're useful and safe
  • 🔎 Reverse-engineering & security review — "what is my app actually exposing?"

Stack: TypeScript · React / Next.js · Node · Python · PostgreSQL · Stripe · Docker · Google Cloud · three.js

Featured work
rag-agent-ts A retrieval-augmented AI agent with per-tenant data scoping, tool-calls, and human-in-the-loop confirmation for writes. Runs offline out of the box.
multi-tenant-saas-rls Postgres Row-Level Security proving one customer can't read another's data — the #1 serious SaaS bug, prevented at the database layer.
interactive-3d-viewer A dependency-free three.js product viewer: orbit, zoom, 9 live finishes.  Live demo »
web-surface-mapper An ethical static analyzer that maps what a web app's JS bundle exposes — endpoints, routes, leaked secrets — for authorized self-audit.

Live in production

goldenrockadvancements.com — including an interactive 3D service powered by the viewer above.

Open to freelance work — full-stack builds, AI features, and app / security reviews.
